“De Kooning: A Retrospective,” at the Museum of Modern Art, is the most piercing, inexhaustible and relentlessly intense full-on career survey I have ever seen in this country. It could only be better by being bigger. Packing the museum’s entire sixth floor with nearly 200 paintings, prints, sculptures and drawings (these last the equals of Ingres, Seurat and Â­Picasso), this retrospective should permanently set the art-historical record straight on this artist.
